It is inductor...marking HU-1M2012-121JT

you can put a pair from different board it will work...

Do you have a diagram or you did something similar?
That was spot on.

Well you can see it from first picture...Missing component is in parallel with standing inductor...Just by looking traces it is all conected to positive lead of dc connector...Filter cap should be connected to the ground from one side,but you can se that the ground side trace is clearly separated... This is very common on these boards...here is diagram from similar board :

You can take it from ny board you have in stock that has input LC filter next to the connector...It really is not that importaant as many laptops doesn`t really have it...A piece of wire could work but it is not professional...

In theory your laptop should work even without second inductor but it could cut off due to overload...
